Correlated Color Temperature measured in degrees Kelvin is the industry way of describing a light’s color. As you heat a piece of iron, it glows red, then white as it gets hotter. An incandescent blub produces light with a glowing filament at about 2700K. This is called warm light, the kind we are accustomed to in our homes. We actually see better for tasks with a brighter white, almost bluish, like being outside on a bright day. Shoplight Solutions offers LED strip in both warm (2700K) and bright white (6500K). Our fixtures are typically 5000K but can be specified with different CCTs.
